Container for storing two products separately and dispensing a mixture thereof

Abstract

Container for storing two products separately and dispensing a mixture thereof comprises a bottle, a hollow cap for the bottle, and a plug which fits into the hollow cap to separate a chamber therein from the interior of the bottle. The cap comprises two depending skirts between which the neck of the bottle is gripped, and a flexible dome connecting the skirts to a spout. The plug is bowl shaped and has a portion projecting into the dome to a point near the base of the spout. When the spout is swung laterally, deforming the dome, part of its lower end strikes the plug, ejecting it from the cap.

What is claimed is: 
     
       1. In a container for storing a liquid product and at least one additional product separately, and for dispensing a mixture of said products, said container comprising: a body for holding said liquid product,   a hollow cap for said body, said cap defining therewithin a chamber adapted to hold said additional product, and an orifice positioned between said chamber and the interior of said body when said cap is in position on said body, and   a separating plug adapted to seal said chamber off from said body,   the improvement which comprises:   an inner skirt formed in said cap encircling said orifice,   a deformable dome formed in said cap above said skirt, and   a relatively rigid dispensing spout connected to the top of said dome said spout being pivotable,   said plug having a lateral wall at least part of which is adapted to be gripped by said skirt and said plug projecting into said dome to an extent such that, when said spout is swung laterally, thus deforming said dome, a part of the spout is pressed against the plug to eject it from said skirt.   
     
     
       2. Container as claimed in claim 1 in which said plug has the shape of a bowl, the bottom of which is directed toward the dispensing spout when the plug is inserted in the inner skirt. 
     
     
       3. Container according to claim 2 in which the end of the plug which is remote from the bottom of the bowl is provided with a peripheral collar which bears on the corresponding edge of the inner skirt. 
     
     
       4. Container according to claim 2 in which the plug comprises a frusto-conical lateral wall portion which is not gripped by the skirt, the diameter of which wall portion decreases toward the bottom of the bowl, the part of the lateral wall which is gripped by the inner skirt being cylindrical in shape and complementary to said skirt. 
     
     
       5. Container according to claim 1 in which the part of the lateral wall of the plug which cooperates with the inner skirt comprises a shoulder on its external surface dividing said wall part into two zones, a first zone of larger diameter carrying a peripheral collar at its edge and which is provided with a snap-fitting ring, and a second zone of smaller diameter which is provided with two sealing rings which frictionally cooperate with a corresponding part of the wall of the inner skirt. 
     
     
       6. Container as claimed in claim 5 in which the snap-fitting ring formed on said first zone snaps behind a retaining ring formed on a corresponding zone of the wall of the inner skirt to fasten the plug in the skirt. 
     
     
       7. Container as claimed in claim 1 in which a part of the cap adapted to be attached to the container comprises an outer skirt encircling the inner skirt and positioned concentrically with respect thereto, the inner and outer skirts defining a groove having a wall provided with a snap fitting flange, the cap being attached to the container by snapping a flange at the end of the neck of the container into said groove. 
     
     
       8. Container as claimed in claim 1 in which the dome narrows toward the dispensing spout and has a wall thickness which decreases progressively in the direction of the dispensing spout. 
     
     
       9. Container as claimed in claim 1 in which the dispensing spout has an axis which substantially coincides with that of the neck of the container, a conical shape, and decreases in diameter toward the end of the spout which is remote from the one connected to the dome. 
     
     
       10. Container according to claim 1 in which the dispensing spout delimits at its upper end an outlet blocked by a sealing plate extending substantially perpendicular to the axis of the spout, said plate being connected by a frangible zone to the dispensing spout. 
     
     
       11. A container according to claim 1 wherein said dispensing spout includes a rigid sidewall, and said part of the spout which is pressed against the plug to eject it comprises an end of the sidewall of the spout. 
     
     
       12. In a container for storing a liquid product and at least one additional product separately, and for dispensing a mixture of said products, said container comprising: a body for holding said liquid product,   a hollow cap for said body, said cap defining therewith in a chamber adapted to hold said additional product, and an orifice positioned between said chamber and the interior of said body when said cap is in position on said body, and   a separating plug adapted to seal said chamber off from said body,   the improvement which comprises:   an inner skirt formed in said cap encircling said orifice,   a deformable dome formed in said cap above said skirt, and   a dispensing spout having a relatively rigid side wall with an upper end and a lower end, and connected to the top of the dome, said sidewall having a length substantially greater than the relaxed height of the dome,   plug ejecting means on said lower end of the sidewall said spout being pivotable so that said ejecting means can engage said plug,   said plug having a lateral wall at least part of which is adapted to be gripped by said skirt and said plug projecting into said skirt in opposed adjacent relation to said plug ejecting means such that, when said spout is pivoted, thus deforming said dome, said plug ejecting means of the spout is pressed against the plug to eject it from said skirt.
